How do i interupt an auto headlight in a 2007 Kia Sedona? I know I have to use a relay but I am not sure how to wire it. Thank you

Depends on the method used to indicate the Headlight switch is in the Auto position.  While I haven't done a 2007 Sedona,
and I can't find any info on your vehicle, on other KIA / Hyundai models, there is a wire ( usually Green ) found at the headlight
switch connector that goes to (-) when in the Auto position.   Use a relay to interrupt that wire during remote start.  Here are the
relay connections.
Relay Pin 85 to R/S Ground When Running output ( aka (-) Second Status, (-) Third Ignition, etc )
Relay Pin 86 to +12V constant
Relay Pin 30 to one side of cut Auto Headlight wire
Relay Pin 87A to other side of cut Auto Headlight wire
Relay Pin 87 not used / insulate

Here is a link to a KIA Optima Pictorial showing the Headlight connector and Auto Headlight wire :
